Evaluation of Groundwater Quality in Balatira Watershed, Atpadi Taluka, Sangli District, Maharashtra.
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
There are 1531 watersheds in the state of Maharashtra. The Balatira watershed (BM 113) covering an area of 278 Km2 forms a part of Krishna river watershed falling in drought affected Atpadi taluka in Sangli district of the state. It is bound by North Latitudes 17o 42’ and 75o 00’ and East Longitudes 74o 42’ and 75o 00’ forming part of the toposheets 47O/11 and 47O/15. Sampling of groundwater was carried out at 35 observation wells in pre-monsoon and post-monsoon periods of 2014 and 2015. The physico-chemical parameters analysed were Na, K ,Ca, Mg, Cl, HCO3, CO3, SO4 and NO3 The concentration of various parameters for potability were compared with those of WHO (2004) standards. The scenarios for the parameters are conflicting but for many parameters the values are within the permissible range. The dominant hydrochemical facies is Ca2+ -Mg2+ -Cl- -SO4 --; Na+ -K + -Cl- -SO4 -- and Ca2+ - Cl- - SO4 -- types. The plot on the Gibbs diagram indicates the samples falling in the rock domain reflecting the role of aquifer chemistry and climatic conditions. The paper bring about various quality aspects in determining the usage of groundwater for various purposes.
